Dry sinus/increase in post nasal drip can definitely be caused by sinus surgery.

The ONLY reason one would ever benefit from a sinus surgery if there is a severe anatomical blockage. Very rarely do people need sinus surgery as it is elective and only so topical medications can get into the actual deeper tissue of the sinuses. However, when widening sinus openings, removing tissue/bone and altering the nasal cavity to be wider, this also causes dryness for a person and completely new physiology to the nose/sinus function. The tight junctures are now gone and air pressure is reduced.

Nasal rinses and sprays do not help because this is not due to anything but taking in more air onto tissues than is physically meant to. The saline dries the tissue more. And much of the mucous people often feel is also due to the fact that the “doors” have been taken off of the sinuses, altering the clearance, so mucous can just plop out into throat without warning.

These sinus surgeries are going to soon be proven one of the worst type of surgery aloud to be recommended to patients. They already changed drastically since the implementation of nasal/sinus surgery 20 years ago. They messed many people up then and since they have just been trying to do these with less damage.

Very wrong surgeries to perform as nasal/sinus issues are 95% of the time systemic issues and not anatomical.

There is a former Stanford trained ENT surgeon whom no longer practices because she witnessed first hand how wrong these are. You can look her up and read her story- Dr. Casey Means
